基于自适应窗口的第三代相干技术在X区块的应用

Application of adaptive coherent processing technique in block X

在构造解释中,断层解释是非常重要的一环。相干体处理技术是辅助解释断层的重要手段之一,相干算法也在使用过程中不断创新改进,每一次改进的目的都是提高断层解释精度。X区块主体位于城区,断裂发育,在现有资料基础上实现断裂更加精细地刻画是勘探面临的主要问题之一。通过探索应用基于自适应的相干处理技术,与老方法对比分析,基于自适应窗口相干处理的相干体对断层的刻画精度明显提高。之后对相干体与地震数据体融合,可以更直观地解释断层,进一步提高了地震资料对断层反映的精度。

In the interpretation of the structure,fault interpretation is a very important part.Coherent data processing technology is one of the important means to assist in the interpretation of faults.Coherent algorithms are also constantly innovating and improving in the process of use.The purpose of each improvement is to improve the accuracy of fault interpretation.The main region of the block X is located in the urban area,and the fault is developed.How to realize the finer characterization of the fracture based on the existing data is one of the main problems facing exploration.By exploring the application of adaptive coherent processing technology,compared with the old method,the coherence of the coherent body based on adaptive coherence processing significantly improves the accuracy of the fault.After the fusion of the coherence data and the seismic data,the fault can be explained more intuitively,and the accuracy of the seismic data to the fault reflection is further improved.
